  Wide Temperature Range Azobenzene Nematic and Smectic LC Materials

  摘要：

  We have developed a series of azobenzene liquid crystals (azo LC) compounds, both multicomponent as well as single component, that possess room temperature nematic and smectic phases. Some of these materials have a wide mesophase temperature range which makes them useful for a variety of practical applications. Two main strategies were used for controlling the temperature range of these mesogenic azo LC materials: 1) chemical modification of azobenzene molecules with different terminal pendants; and 2) development of multicomponent compositions. These materials were highly photosensitive exhibiting nonlinear refraction and transmission at nanowatt/microwatt power levels. Physical, electro- and nonlinear-optical parameters of many of these materials have been characterized in detail.

  The reactions of aryliminodimagnesium [ArN(MgBr)(2)IDMg] with p'-substituted p-cyanobenzophenornes, 1-cyano-9-fluorenone, o-, m- and p-dicyanobenzenes and o-, m- and p-nitrobenzonitriles were examined, and the relative yields of products were referred to the previous results of electron spin resonance studies. The products of condensation with carbonyl and nitro groups and of addition to cyano groups were formed. From the variations of the yields caused by the molar ratio of the magnesium reagent versus substrates and by the substituents of both reactants, the preferred groups were determined, The groups of p- and m-substrates are consistent with the position of highest density of free electrons in the anion radicals, whereas those of the o-substrates are inconsistent. The consistency indicate competition of functional groups reflecting the relative ability of single electron acceptance from the reagent, whereas the inconsistency is ascribed to cooperation of neighbouring groups for sigma-complexation with the Mg atom of the reagent, The categories of competition and cooperation are discussed in relation to fundamental features and general governing factors proposed for the IDMg reactions of monofunctional substrates.
